Wire stretcher



DAVID H. ALLEN, OB SULFUR, G'LORATDO.

WIRE STRE'ICI'IER.

Application fi1ed November 27, 1920.

T0 all 107mm z'zf may conaem:

Be it known that I, DAVID H. ALLEN, a citizen of the Unitecl States, 1esiding ab Sulfur, in the county of Rio Blanco, Statue of Colorado, have invented new and useful Improvements in Wire Stretchers, of which the following is a specification.

lt is the object 033 his invention to p10 Vide a Wi1'e stretche r of extremely simple construction and adapted to be readily placed in operative position, and actuated f01 stretching a wire and then retainihg the 1atter in ics stretched condit-ion.

The inventiou Will be readily understood from the following description of the accompanying drawi ngs, in which:

Figure 1 is a plan view showing the wire stretcher applied to a wire.

Fig. 2 is a similar view after the wire has been stretehed and showing the stretcher in positiom f'or retaining the wire in ics stretched condition.

Figs. 3 and 4 are end views of the wire stretcher with the latter in the positions shown in Figs. l and 2 respectively.

Fig. 5 is a section on the line 55 of Fig. 3.

Fig. 6 is an end view of the wire stretcher taken from the opposite end .frorn that sh0wn in Figs. 3 and 4.

The improv'ecl Wire stret-cher is an integral structure comprising a hub 1 having the disc 2 projecting f10m the same intermediate of its ends. The disc 2 is provided with a peripheral flange 3 extending towa1d end 5 0f the hub of the stretcher, and this fiange is provided around its circumference with inclined notches 4.

The end 5 0'f the hub is transversely s1otted. as shown aty6, said s1ot extending to a suitab1e depth within the hub, and the end 5 may also be provided with a peripheral beading 7 at its oute r end. The junction of the end portion 5 of the hub with disc 2 also provides a peripheral beading 7. By this arrangement the end portion of the hub betvveen the beadings forms a real 012 which wire may be wound.

The opposite end of the hub shown at 8 is arranged as 21 head adapted to be received by a suitable socket wrenvh o1 cmnk Specification of Letters Patent.

handle, and in the present embodiment of the invention this head is shown as 21 squa1e head in cross section.

The wire 120 be strecched is shown at 10, and in operation the stretcher is positioned With ehe wire received in ehe base of s1ot 6. The slot pleferably extends to such a depth that its base is in alinement with disc 2, and the wire 10 is thereby positioned adja cent the flange 3. The head 8 is then engaged by a suitab1e handle 01 wrench, and is rotated so as t0 Wind the wire 10 upon the real forrned by the stretcher, und as a consequence the wire is strecched. The stretcher is 10tated in the direction 0f inclination of notches 4, so that after the wire has been suitably stretched by engaging the ends thereof in notches 055 flange 3.- reverse rotation 0f ehe stretcher Will be prevented by this engagement of the wire ends with in the notches. The stretcher is thns securely he1d against unwinding, and as 21 eonsequence the wire is maintained in its stretched condition.

If it is desired to subsequently release the wire, it is on1y necessary to axia1ly shift the stretcher until the wi1e ends are disengaged from notches 4:, so that the stretcher is free for reverse rotatioi1. After the stretcher is thus reversely rotated, it may be readily removed from the wire by removing the latter from slot G.

Thus it Will be seen that I have provided a wire stretcher readily attachable to anti remomble from a wire and arranged t0 provide 'f01' stretching the wire and retnining the laccer in stretched condition.

Various changes may be made without departing from the spirit of the invention as claimed.

What is claimed is:

l. A wire stratcher comprising a hub having s, slotted end, means at the other end 0f said hub f01 rotating the same, and a disc on Seid hub having inclined peripheral notches extending toward the slotted end of the hub.

2 A Wire stretcher comprising a hub having a slotted end, and a disc 0n said hub having a peripheral flange extending toward fixe slnfted end 0f the hnb, sm'd flange havspaced notches therein, the other end of said S101:- ted hub and the junction of said hub with said disc forming peripheml beads 011 said 10 hub arranged 150 provide a real.

In testimony whereof I have signed my name to this specification.

DAVID H. ALLEN.
